Manual MIDI mapping

The MIDI learn function is great, but it would be good to also be able to manually map MIDI commands.
I have had instances where I want to trig on Note On messages but it has mapped Aftertouch instead.
I have also had instances where I want to map “Bypass” to “Note ON” for one pipe and “Bypass” to “Note OFF” on another pipe for the same note.
In these instances more deliberate manual MIDI parameter editing would have been great!
